[Morphofunctional characteristics of the placenta, placental bed and myometrium in abnormal labor activity].

By comparison of dopplerometry results of right uterine artery and umbilical cords of a fetus with the histologic and morpho-stereometric data studies of the placenta, and also placental bed and myometrium in an operational material at Cesarian sections, a morphological basis of disturbances of communications in a functional system "mother-placenta-fetus" in hypotonic and hypertonic dysfunction of the uterus is revealed. The morphological picture of chronic placental insufficiency of the fetoplacentary form in the presence of pathological chorion immaturity is revealed in the development of weakness of activity. The uteroplacentary form of chronic placentaly insufficiency, incomplete gestation reorganization MPA and reduction morphometric parameters of a vascular channel miometrium documented formed discoordination of uterine muscles at child birth.
